My invention relates to pulleys and more particularlyto thatcla-ss employed in connection with the operationand manij'oulation of awnings. The principal object ofthe invention is to provide a' compact, simple and easily adjustable device of this character capable of operating in a manner such th the friction usually gei'ierat edf between an awning cord or string and. its cooperating fixture is reduced minimum. A further object of the invention is to construct a device which may be readily installed without the aid of cumbersome wall attachments.

A primary feature of theinvention consists in providing, in combination with a ring-like member having a threaded projection, a rotatable pulley disposed within said member, and a frame for supporting said pulley, the said frame being pivotally secured to the said member. f

A further feature of the invention resides in fashioning a screw eye with a plu rality of oppositely extending studs and in associating therewith a plurality of means respectively mounted on said studs, each of said means. involving a rotatable pulley and member fashioned with a threaded projection 2, the, latter forming means for effectively attaching the ring member to any desired support. As is well known, the parts land 2 constitute what is commonly termed a screw eye. Opposite the threaded projection 2, the ring-like member is provided with a portion 3 of preferably rectangular cross section, thus presenting aypluralityof substantially fiat surfaces A plurality of pulley frames 5 are respectively'pivotally connected to opposite faces of the rectangular portion 3 of the ring member 1 in a manner such that one of said frames is disposed within and encompassed UM?! so s rArss P A TENT o Pr mr.

by the ringfthe pivotal axis of both of said frames being substantially normal to the axis.

of the ring. 5 These frames are respectively pivotally connected to, the ring member by studs 6 wh ch are disposedi-substantially centrally of'and pr'ojectfrom the afo rementioned flat surfaces 1, the studs being advantage- .ously formed integrally with, the member ,1. The outer, ends of the studs 6 are upset-as at 7 to preveiitthe names 5 frombecoming accidently disconnected therefrom." To obviate undue wear between the frames and ring 1 washers 8 are preferably interposedv therebetween. I

- R'otatably journaled in the frames by means of pins 9 having enlarged or upset ends 10 are pulleys or rollers 11, each of which is fashioned with a concave periphery 12 to accommodate the usual awningcord or string (not shown). As illustrated in Fig. 8, in cases where it is not requiredthe pulley and its cooperating stubwhich is located without the ring 1, may be readily discarded.

The devices as illustrated are preferably designed to be attached or secured by the threaded projection 2 as wall or other means'of support so that thepivotal axis of each of the pulley frames 5is substantially vertical or, in other words, so that the axis of rotation-0f the pulleys is substantially hor- 'izontal. By this arrangement it will be ap preciated that the pulleys will respond to the pressure applied to them by the awning cord r or the like so as to readily adjust themselves andassume a position such that the awning may be operated with a minimum of effort.

This free and automatic adjustment of, the to Fig. 1, the V pulleys in response to force applied thereto by the awning cord obviates the great waste of cord occasioned by drawing the latter over relativelystationary or immovable parts.

In addition to screw eye affords simplicity of'adiustment and dispenses with cumbersome wall attachments heretofore employed in connection with pulleys of any description.

. I claim I 1. In a device of the character described, the combination with a ring-likev member having a threaded projection, of a rotatable pulleyidisposed within said member, and a frame for supporting said pulley, said frame being pivotally secured to the said member.

2. In adevice of the character described,

the ofliceof support, the

lli)

the combination with a ring-like member having pulley means to the said member, the axis of the latter 5 being substantially normal to the pivotal axis of said means.

3. In a device of the character described, the combination with a ring-like member having a threaded projection, of a' rotatable pulley disposed within said member, a "frame for supporting said pulley, and means integral with said member for pivot-ally connecting the frame to said member.

4. In a device of the character described, the combination with a ring-like member having a threaded projection, a portion of the inner surface of said member being sub stantially flat, of a rotatable pulley disposed within said member, and a pivotally mounted frame for supporting said pulley, the fiat a threaded projection, of a rotatable.

portion of said member being formed with means for pivotally connecting the frame to the latter.

5. In'a device of the character described, the combination with a screw eye having a rotatable pulley disposed therein, of a frame for supporting said pulley, said eye being provided with an inwardly projecting stud constituting means for pivotally connecting the said frame to the eye.

6. In a device of the character described, the combination with a ring-like member having a threaded projection and being fashioned with a plurality of oppositely extending studs, ot a plurality of means respectively mounted on said studs, each of said means involving a rotatable pulley and a frame constituting a support for the latter.

In testimony whereof I aflix my signature.
